JUXTA M Series Signal Conditioners

An "easy adjustment" function has been added to improve serviceability. When indicated values are aberrant, this function allows you to use an adjustment driver to add offset or gain to the output values. This prevents two problems that commonly occur when performing adjustments with analog converters: 1) backlash (switches returning to previous settings after being changed); and 2) the problem that zero point adjustment can affect the span adjustment, or vice versa.

[Affected Models]
MA5 Distributor (1-output), MA5D (2-output, isolated), MH5 Isolator (1-output), MH5D (2-output, isolated), MU5 universal temperature converter (1-output), MU5D (2-output, isolated) MS5 Potentiometer Converter (1-output), MS5D (2-output, isolated)

1. Apply an input signal to the converter.
2. Open the converter's front panel cover and set the adjustment selection switch to 1. 　When the switch is set to something other than 0 the unit enters the "adjustment mode" and the operation indicator lamp in the upper right blinks.
3. Turn the adjustment switch to obtain the desired output value. Turn the switch quickly for larger increases. Change the input signal and check that the desired response is obtained.
4. Finally, return the selection switch to 0 and close the converter cover to conclude adjustment. 　The operation indicator lamp returns to the illuminated state.
